Overrides the linkers used for kvazaar, libkvazaar.la and kvazaar_tests.
When crypto++ is enabled, the C++ linker is used and when it is
disabled, the C linker is used.
This removes the need to explicitly specify -lstdc++ in configure when
crypto++ is used and fixes the build with crypto++ when libstd++ is not
installed.
Add md5 through extras/libmd5 taken from HM with BSD license. It's
implemented as a generic strategy using the same interface as checksum,
so we can write a SIMD version if it seems necessary.
Prevents a conflict with config.h and src/config.h so that the config.h
generated by configure is included in global.h. Fixes problems with
large input files on 32-bit systems.
Option -mavx2 was omitted when compiling AVX2 strategies. This commit
moves strategies to convenience libraries so that their compilation
flags can be easily set and adds -mavx2 to CFLAGS of the AVX2 library.
